Abstract

The invention relates to a supporting roll for a belt conveyor, consisting of a hollow-cylindrical roll casing (1) which is connected at each of its two ends to a roll base (2), and a stationarily supportable shaft (12) on which the roll bases (2) are mounted by means of lubricant-filled and -sealed ball bearings. For cost-effective production, each roll base (2) forms with the ball bearing and with sealing fittings (7, 10) a preassembled subassembly with a closed lubricant chamber.

Description

Die Erfindung betrifft eine Tragrolle für einen Gurtförderer mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen. Eine solche Tragrolle ist aus der DE-AS 22 17 062 bekannt.The invention relates to a support roller for a belt conveyor with the features mentioned in the preamble of claim 1. Such a idler roller is known from DE-AS 22 17 062.

Bei der bekannten Tragrolle werden zunächst die Kugellager vor inneren Dichtringen auf der Achse montiert. Danach er­folgt die Schmiermittelfüllung, und es wird ein weiches Element einer Labyrinthdichtung aufgeschoben. Das Gegenele­ment ist an den Rollenboden angeformt, der dann auf die Achse gesetzt und zugleich in den Mantel eingepreßt wird.In the known idler roller, the ball bearings are first mounted on the axle in front of inner sealing rings. Then the lubricant is filled and a soft element of a labyrinth seal is pushed on. The counter element is molded onto the roller base, which is then placed on the axle and at the same time pressed into the jacket.

Bei anderen bekannten Konstruktionen (FR-PS 843 732, BE-PS 518 680) ist im Innern der Tragrolle ein größeres Reservoir für Schmiermittel vorgesehen, das bei der Montage verschlos­sen wird. Bei einer marktgängigen Tragrolle (Fabrikat Krupp) schließlich ist eine von Dichtungen begrenzte Schmiermit­telkammer vorgesehen, die jedoch ebenfalls erst dann ge­schlossen ist, wenn das Lager auf der Achse montiert ist, so daß es auch erst dann mit Schmiermittel versorgt werden kann.In other known constructions (FR-PS 843 732, BE-PS 518 680), a larger reservoir for lubricants is provided in the interior of the support roller, which reservoir is closed during assembly. In the case of a commercially available idler roller (manufactured by Krupp), a lubricant chamber limited by seals is provided, which, however, is also only closed when the bearing is mounted on the axle, so that it can only then be supplied with lubricant.

Aufgabe der Erfindung ist es, eine Tragrolle der eingangs genannten Art zu schaffen, deren Herstellung besonders ra­tionell erfolgen kann. - Diese Aufgabe wird gemäß der Er­findung durch das im Anspruch 1 definierte Konzept gelöst; die Unteransprüche beziehen sich auf bevorzugte Ausgestal­tungen dieses Vorschlags.The object of the invention is to provide a support roller of the type mentioned, the production of which can be carried out particularly efficiently. - This object is achieved according to the invention by the concept defined in claim 1; the sub-claims relate to preferred embodiments of this proposal.

Die beigefügte Zeichnung stellt im Radialschnitt ein Ende einer erfindungsgemäßen Tragrolle dar. Sie umfaßt den Rol­lenmantel 1, der mit seinen Enden an Rollenböden befestigt ist, z.B. aufgeschrumpft ist; die Zeichnung läßt einen Rollenboden 2 erkennen. Der Rollenboden 2 ist außen leicht konisch, damit hereinfallende Partikel leichter ausgeschleu­dert werden, und weist auf seiner Innenseite einen äußeren Flansch 3 auf, der den Mantel 1 abstützt, sowie einen inne­ren Flansch 4. Dieser nimmt das Kugellager mit Innenring 5 und Außenring 6 sowie die Dichtungsgarnituren auf. Ein in­nerer Dichtring 7 ist mit seinem Radialabschnitt zwischen einer Stufe 8 des Rollenbodens und dem Außenring 6 des Ku­gellagers eingeklemmt und liegt mit einem axialen Bund am Innenring 5 des Lagers an. In eine Innennut 9 des Flansches 4 ist ein zweiter Dichtring 10 eingesprengt, der mit seiner Dichtlippe auf der anderen Seite des Kugellager-Innenrings 5 abdichtend anliegt. Bevor das Lager im Rollenboden einge­setzt worden ist, wurde noch eine schmutz- und wasserabwei­sende Dichtung 11 in eine Ausdrehung des Rollenbodens ein­gelegt.The attached drawing shows in radial section one end of a support roller according to the invention. It comprises the roller jacket 1, which is attached at its ends to roller bases, e.g. has shrunk; the drawing shows a roller floor 2. The roller base 2 is slightly conical on the outside, so that falling particles can be thrown out more easily, and has on its inside an outer flange 3, which supports the jacket 1, and an inner flange 4. This takes the ball bearing with the inner ring 5 and outer ring 6 and the Sealing sets on. An inner sealing ring 7 is clamped with its radial section between a step 8 of the roller base and the outer ring 6 of the ball bearing and rests with an axial collar on the inner ring 5 of the bearing. A second sealing ring 10 is blown into an inner groove 9 of the flange 4 and bears with its sealing lip on the other side of the ball bearing inner ring 5 in a sealing manner. Before the bearing was inserted into the roller base, a dirt and water-repellent seal 11 was inserted into a recess in the roller base.

Vor dem Aufschieben des Rollenbodens auf die stationär ge­haltene Achse 12 wird die Kammer, begrenzt von den Kugella­gerringen und den Dichtringen, mit Schmiermittel gefüllt. Beim Aufschieben auf die Achse 12 legt sich der Kugellager­innenring 5 an einen Bund 13 der Achse an und wird dort ge­halten, sobald die Verbindung zwischen Rollenmantel und Rollenböden hergestellt ist.Before the roller base is pushed onto the stationary axis 12, the chamber, delimited by the ball bearing rings and the sealing rings, is filled with lubricant. When pushed onto the axle 12, the inner ball bearing ring 5 rests against a collar 13 of the axle and is held there as soon as the connection between the roller jacket and roller bottoms is established.

Die Tragrolle gemäß der Erfindung hat einen sehr einfachen Aufbau; so ist nur die eine Stufe 13 an der Achse vorzuse­hen, und das Lager kann fertig geschmiert aufgeschoben wer­den. In erwünschter Weise wird der Rollenmantel möglichst weit außen abgestützt, so daß Biegeverformungen der Achse klein sind.The idler roller according to the invention has a very simple structure; only one step 13 has to be provided on the axle, and the bearing can be pushed on and lubricated. In a desired manner, the roller jacket is supported as far as possible on the outside, so that bending deformations of the axis are small.

Man erkennt in der Zeichnung auch, daß der Flansch 3 eine Eindrehung 14 aufweist, in die das Ende des Rollenmantels 1 eingewalzt sein kann; dies erlaubt, die Axialerstreckung des Flansches kurz zu wählen und damit Material zu sparen.It can also be seen in the drawing that the flange 3 has a recess 14 into which the end of the roller shell 1 can be rolled; this allows the axial extent of the flange to be selected briefly and thus saves material.
